` VALVE FOR BOTTLE-FILLING APPARATUS.

Specication of Letters Patent. Paftnted Api', 1ML, 1914.

Application fuea may 7, 1912. serial No. 695,620.

To all whom t may concern Be it known that I, HENRY W. VAN-Lanz, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Valves for Bottle-Filling Apparatus, of which the following is a specification.

My invention relates -to bottle vfilling valves of that type in which the valvey slides.

on the filling tube, and is opened by the upward pressure of the bottle or jar and closed by the action of a spring or equivalent device against a seat4 carried by an air vent tube which passes up through the filling tube, the objects of my invention being to provide for the proper support of the air vent tube while permittingof the ready insertion and removal of the same, to insure a tight closing valve, and to provide forl the pro er escape of the air' from the interior o the bottle during the filling operation.

In the accompanying drawing Figure 1 is a; vertical sectional view of a valve for bottle filling apparatus constructed in accordance withl my invention, the'valve being shown in the closed position; Fig. 2 is a similar view showing the valve in the open' position, and Fi 3 is 'a perspective view of the air vent tu e supporting device.

In the drawing, 1 represents part of the bottom of a tank for containing the liquid i with which the bottles are tobe filled, saidtank wie having a number of depending nipples such as shown at 2, each of these nipples being threaded at its lower end, as shown at 3, for the reception-of a coupling nut 4, whereby the anged upper end of thefillin'g tube 5 is firmly conned to the lower end of the ni ple.

assing through the filling tube 5 is an air vent tube 6, which issupported at its upper end by means of a cage 4contained in the interior of the tank and comprising a base ring 8 adapted to a countersunk recess 12 in the bottom 1 of the tank and having upwardly projecting legs 9 which rigidly and ixedly support a ring 10 having an openingv or gap 10",in one side, as shoyvn in Fig. 3, and having at the top a seat 11 for receiving a collar 6a at the upperA end of the vent tube 6, as shown in Figs. l and 2. Secured to the lower end .of the vent tube 6 is a plug 14 having, a truncated conical upper face 15 and a-truncated conical lower face 16, and ybetween these upper and' lower faces is a seat 17 for the valve 22,

vertically on the filling tube 5, and is normally moved downwardly on said tube, so as to cause the valve 22 to bear upon the seat` 17, by means of a ,coiled spring 23 or equ1valent`device, said coiled spring being interposed between the underside of the coupling nut 4 and an annular flange 24 projecting from the tube 21 and having an outen vertical ange 25 projecting above and below the flange 24, the upper projecting portlon surrounding. a recess 26 which recelves the lower portion of the spring 23, and thelower projecting portion surrounding a recess which receives a gasket 27 of rubber or otherelastic material, for sealing the mouth of the bottle or jar during the filling operation. The flange-25 has a drainage opening 28 therein and the ange 24 has an -opening 29 forthe passage of a suitable tool whereby the gasket 27 may be dislodged when desired.

The plug 1'4 is supported upon the lower end ofthe air tube 6 by outwardly flaring the lower end of said tube, as shown at 18, into the correspondingly flaring lower end of the central opening formed in the plug' 14 for the reception of the tube 6, and in said plug, above the bottom of the latter,.are formed radiating openings 19 registering with openings 20 in the tube and providing passages for the inflow of air to said tube after its'lower end has been sealed by the rise of the liquid in the bottle during the ,the plug .and correspondingly; aid in preventing: leakage between the two when the valve-is closed.

The normal position of the parts is the v closed vpositionfrepresented in Fig. l, but

when a bottle is, raised beneath the valve the mouth of said bottle first strikes the under face of the elastic gasket 27 and thereby seals said mouth, further upward movement vof the bottle causing the lifting of the valve against the pressure of the spring 23 and thereby permitting the flow of liquid from thelling tube 5i-nto the bottle through the annular space between the valve and its seat, as shown in Fig. 2. -As -the liquid enters the bottle lthe air can escape from the latter through the vent tube 6 until the level of liquid rises in the'bottle` to such point as to .close the `vent openings 19, whereupon further risexof the liquid will trap the air in theuppelnportion of the bottle and will compress the same'l until it counterbalances the pressure of the hydrostatic column of liquid in the illing tube and tank, whereuponrv lfurther entrance of liquid into the bottle-is'farrcsted. As the filled bottle is lowered the valve 22 descends with the same until it is finally again seated upon the plug 14, thus closing communication between the interior of the bottle and the lilling tube. The collar at the upper end of the vent tube 6 and the plug at the` lower end of the same are secured to` said tube before the application of thesame to the sup-- porting cage, hence the provision-of the side vop'enin or gap in the ring"l0 so that the vent tu 'e can be introduced froml below and at an angleuntil the collar at the upperend of said tubeis above the ring 10, whereupon i Witnesses:

the tube can beipassed through said opening untilit has assumed a vertical position and the collar at the upper end of .the tube can -be dropped into its seat 11 inthe top of the ring.

I claim:

1. The combination, in a bottle filling apparatus, of a-'lilling tube, a valve, an air vent tube passing through said filling tube and having at its upper end a supporting collar and `at its lower end a plug having a seat for the valve, a ring having a seat for said supporting collar and a side opening through which the filling tube can be'passed laterally, a support for said ring and legs extending downwardly from said ring to said support and serving to rigidly and ixedly mount the ring.

2. The combination of the tank having an opening therein, and a counter-sunk recess surrounding said opening, a filling tube, a f valve therein, an air vent tube having a seat l for said valve, a support for said tube ca'rthe seat therein.
